You can implement custom rendering they way you wish

<% template divrender(cppcms::form &aform) %>
 <% foreach w as cppcms::form::iterator in aform %>
        <% item %>
             <div>
                <% if w.has_message() %><%= w.message() %>:<% end %>
                <% form input w %>
                <% if not w.valid() %>:<%= w.error_message() %><% end %>
             </div>
        <% end %>
 <% end %>
<% end template %>

Yes because cppcms::form iterator iterates over all sub-widgets tree.

Organize widgets into subforms and render them separately.


   <div>
    <% include divrender(form1) %>
   </div>
   <div>
    <% include divrender(form2) %>
   </div>

You can also put the pointers/references on them in sime
list/array and use foreach
